IMPROVED MACHINE roe FILLING PAINT-SANS.

TO ALL WHOM I'I MAY-CONCERN:

Be it known that I, JOHN WILOOX, of Springfield, in the county of l'l ampden, and State of Massachusetts, have made and invented certain newand useful Improvements in Machines for Filling Paint-Cans, and other similar purposes; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the-annexed drawings, making a part of this specification, in which- I Figure 1 is a perspective view.

Figure 2 a sectional viciv of the filling apparatus, and

Figure 3 a perspective view of the adjustable collar and flange.

My invention relates to an improved machine for filling ground paints, or other substances of similar consistency, into cans or vessels, and is designed to facilitate such operations, by putting a specific and ascertained quantity into each can or vessel, without any weighing-or measuring other than that'performed by the machine itself, after once being properly adjusted to any given substance and quantity.

The nature of my invention consists in providing the central shaft, to which the stirrer is'attached, with one, two, or more movable collars, such collars being further provided with an adjustable ring, which may be set at any desirable angle of inclination, according to the consistency of the substance to be impelled thereby; and further, in providin'g, in connection with the tunnel, a revolving cylinder and an accompanying plunger, so arranged that, on the withdrawal of the plunger, the paint or other substance in the tunnel is forced, by atmospheric pressure, into the cylinder, when, by a semi-revolution thereof, and a return stroke of the plunger, the

. paint or other substance is ejected from the nozzle into the can or vessel.

And, in carrying my invention into practical operation, I construct a strong frame, A, covered by a table or rest, B, through which is a large circular hole, wherein I setthe tunnel C or other suitable receptacle for the paint. To the tube a, of the tunnel O, I attach, by brazing or other suitable means, a ring or collar, 6, and on to the ring I), which is provided with athread, I screw the angle-box D, which box I construct with both a vertical and a horizontal opening, the vertical opening being of about the same size as the tube a, while the horizontal opening, which is round, I make somewhat larger, or of sullicicnt diameter to allgw the insertion and easy revolution of the cylinder E; and in two sides of the angle-box, or around each end of the horizontal opening therein, I form a recess, in each of which I place a packing, a c, of leather or other suitable material,

To the bottom of the angle-box, or into the vertical opening thereof, I screw the nozzle d, which I further extend by means of a small pipe, 0?.

I make the cylinder E from ten to twenty inches long, and from three to six inches, more or less, in diameter. One end thereof I construct smaller than the other, thus forming a shoulder about midway, the small end being closed while the large end is left open, as seen in fig. 3. On one side of the small end of the cylinder I make a circular aperture of about the same size as the tube a, and then, placing the packings c c in the recesses provided therefor, and passing the small end of the cylinder through the horizontal opening of the angle-box, till the shoulder on such cylinder rests against the packing a, I thus secure it by means of the not 0 and cheek nut c, seal-ranging the nut e and check-nut c" as to form, in combination with the packing c,'a practically tight joint without materially impeding the revolution of the cylinder E, which is operated by means of the handle, F, attached thereto, as seen iufig. 1.

And further, I construct a rest, G, in which I make a slot or opening, f, running lengthwise thereof, one end of which rest Iattach to the angle-box D, while the other end is supported by a cross-bar or stretcher, in the frame A, as seen in fig. 1;

The outer end of the rest, G, I provide with a perforated elevation, g, For the support and guidance of the plunger-rod 7L, and to one end of the rod 72, I attach the plunger II, which I construct of such a size as to fill the interior of the larger part of the cylinder E, or as nearly so as maybe, and still allow the plunger a free and ready stroke. i

And further, I construct or provide the rod 7 with apin or projection, c, on the lower side thereof, and extending downwards into the slotf, wherein it moves. I also provide stops 2' t", which I arrange and secure, by means oi set-screws, at any desired point along the slotf.

, For the purpose of" operating the plunger, I provide and attach, to one side of the red It, a straight gear, 1:. I also provide awhecl, m, meshing into the gear 7:, such wheel turning on a pivot in the rest G, and being moved by means of the handle PIC provided for that purpose,

I also provide a central shaft, J, which rests in the step a, and is operated by the bevel-gear L, and to the side of the shaft J, I attach an ordinary stirrer, 0. I

I also provide one, two, or more collars, M, fig. 2-, which I place around the shaft Luear the lower end thereof, securing them atany desirable point by means of a set-screw, P, and I provide and attach to one side of such collars What I term'an adjustablewing, g, which may be arranged at' any desired angle of inclination, and thus secured by means of the nut r.

My improved machine being thus constructed and arranged, it will be seen that it depends principally on atmospheric'pressure for the drawing and measuring of the paints or other substances. Alljoints, therefore, around the measnring-apparatus must bepractically air-tight, and if not so at the commencement of operations, they will soon become so by the action of the paints or oth er similar substances, which not both as a packing and a lubricator. I

The machine is set in motion by belting on to the pulleys N N, the former of which is loose and the latter fast on its arbor, and paint being put in the tunnel, it is kept in motion by the stirrer, whereby it is warmed and made thinner, while the adjustable wings tend to work it downward towards the cylinder, and in filling cans, the operator, by means of the handle F, has only to turn the cylinder till the aperture on the side thereof communicates with the tunnel, when, by a backward stroke of the plunger, the cylinder is filled; then, turning the cylinder half way over, or till it communicates with the nozzle, and, by a reverse or forward stroke of the plunger, the paint is ejected into the can or other vesscl. v I

The length of the stroke, and, at the same time, the heft oi the eharge,'arc regulated and determined by means of the stops across the slot -in the rest, in conjunction with the pin or projection on the plunger-rod. The stops may be set at any required distaneewithin the limits of a given machine, according to the heft and consistency of the substance in the tunnel. The length of the stroke necessary to put a specific quantity of any given material in a can must be determined at first by experiment. I find, from experience, that my machine works betterwhen the plunger is not driven in till stopped by the shoulder in the cylinder. It should, therefore, be brought to rest a little before reaching that point.

I construct the frame of my machine of wood, the rest of iron, except the packings, which I make of leather. The dimensions may be varied according to circumstances. I

Having thus described my improvement, and how' the same is to be constructedpwhat I claim as my invention, and for which I wish to secure Letters Patent of the United States, is-

1. I claim the adjustable wing q, when constructed and arranged substantially as described, and for the purpose specified.

2. I claim the movable collar M, in combination with the wing q, shaft J, and tube a, substantially as described, and for the purpose, specified. 1

3. I claim the angle-box D, when recessed as described, in combination with the tube a and cylinder E. substantially as described, and for the purpose set forth. I

4. I claim the cylinder E, when constructed with a shoulder and side aperture, as described, in combination with the angle-box l), packings c a", nut e, and check nut a, substantially as specified, and for the purpose set forth.

5. I claim the packings c c',',when constructed and arranged in the manner described. and for the purpose specified.

6. I claim the rest G, constructed and arranged as described, and for the purpose set forth.

7. I claim the stops ii, in combination with the slotted rest Gr, rod it, and pin a, as and for the purpose. specified.

' 8. I'claim the red It, when provided with a pin, '8, in combination with the rest G, plunger H,-and cylinder E, substantiallyas described, and for the purpose specified.
